Title: Method and device for preventing ignition of gas discharged from high pressure ethylene polymerization plant in emergency
Inventor: MIYAKE AKIRA
IPC: B01J19/00
Filed: 1978-09-05
Abstract: PURPOSE:To prevent the ignition of gas discharged from ethylene polymerization plant, by contacting the content of the reactor with a large amount of water to form a mixed phase flow, and expanding the hot ethylene gas adiabatically in an inert gas atmosphere, thereby decreasing the temperature of the reaction product below the ignition temperature. CONSTITUTION:When the pressure in a reactor 1 for the polymerization of ethylene at e.g. 100-400 deg.C and 1000-4000kg/cm<2>, exceeds the preset value of a safety valve 2, the hot gas in the high-pressure vessel C is blasted to the discharge tube 3 at the low-pressure side D as a shock wave. The discharge tube 3 is filled with an inert gas such as nitrogen gas, and holds a large amount of water. The amount of water is 0.25-2 weight times that of the content of the reactor 1. The content blasted through the valve to the discharge tube 3 is contacted with the water to form a mixed phase flow, and the temperature of the reaction mixture is lowered below the ignition point of the mixture. After the adiabatic expansion, the mixture is discharged to the atmosphere.

Title: Alignment device
Inventor: OUTSUKA KAZUHITO
IPC: G01B11/00
Filed: 1987-05-06
Abstract: PURPOSE:To enable positions in picture images without interference band to be detected by a method wherein the second element such as a wafer is illuminated not through the intermediary of a projection optical system PO to collect the picture image data from the images through the intermediary of the projection optical system of the second element by the illuminating light. CONSTITUTION:The images illuminated by a wafer lighting system WL are converted into electrode signals by an ITV camera or solid image sensing element (CCD), etc., to be digitized by an A/D converter ADC for storing in a frame memory FME as picture image digital data. Paying attention to the picture image digital data in respective linear mask directions, data are projection-integrated in X or Y direction by the length as necessary using a projection integrating window. Any relative slip amount between a mark of reference mask and a wafer mark is calculated by maintaining the balance of projection data thus collected. At this time, sufficient precision is assured by maintaining the balance of integrated data due to no interference band in the formed image. Consequently, any specific hardwares are unnecessary for any parts excluding the part to be XY projection-integrated making it feasible to measure any slip amount at high speed with high precision.

Title: Light receiver for surface inspection machine
Inventor: HACHIKAKE YASUO
IPC: G01N21/956
Filed: 1985-05-23
Abstract: PURPOSE:To prevent drop in the sensitivity in the perimeter of a wide scanning zone, by arranging two lens elements on the same plane in the lens on the side of projection point among two Fresnel lenses separated facing each other in parallel. CONSTITUTION:The sensitivity lowers as a spot light source P on a scan line 1 is separated from the center of a lens but the decrease in the amount of transmission light is prevented by arranging two lenses 3a and 3b parallel to the scan line to reduce the incidence angle with respect to the lenses. The use of Fresnel lenses makes the equipment thinner with a larger diameter and the machinability can be improved by being made up of an acrylic resin. The point P biased to the right on the scan line 1 is located near the front of a lens element 3a-2 and emission lights (c)-(e) are allowed to pass therethrough 3a-2 with such a large transmittance that they may converge with the lens 3b toward the focus of the lens element 3a-2 and gather at the point Q on a light-receiving surface of the element 2. The same is with the point P' biased to the left. The number of the Fresnel lenses 3a may be three. The lens 3b may be composed of a plurality of lens elements. The addition of a Fresnel lens 4 is possible.
